+Implementation start failure / recovery note:
+
+`queued -> inprogress` acceptance と worktree 作成は完了したが、Coder Pod spawn に失敗した。
+
+Created worktree:
+- `/home/hare/Projects/yoi/.worktree/00001KV5W3PHW-plugin-wasm-tool-runtime`
+- branch: `impl/00001KV5W3PHW-plugin-wasm-tool-runtime`
+
+Failure:
+- `SpawnPod` failed before child Pod creation.
+- Error: `failed to spawn /home/hare/Projects/yoi/target/debug/yoi (deleted) pod: No such file or directory (os error 2)`
+
+Interpretation:
+- Runtime binary path for this long-lived Orchestrator process points at a deleted executable. This is an operational/runtime issue, not a Ticket requirement issue.
+- No Coder Pod was started and no implementation commit exists in the child worktree yet.
+
+Recovery needed:
+- Refresh/restart the Orchestrator runtime or provide a valid Pod runtime command so `SpawnPod` can launch children again.
+- After recovery, reuse the existing child worktree/branch if clean and resume Coder spawn for this in-progress Ticket.
+
+State handling:
+- Ticket remains `inprogress` because acceptance and worktree side effects already happened; it is not silently returned to `queued`.
